“Wonchubyeo” is a new japonica rice (Oryza sativatute (KAERI) and was released in 2004. In order to select the mutants of Chucheongbyeo with god traits, the seds were ira-diated with 250 Gy gama ray (83.3 rad/min) emited from 60Co in a radiation facility

Scrophularia takesimensis Nakai called "Sum-Hyun-Sam", growing about 1m in high is a perennial plant of Scrophulariaceae. Because the number of these species is very limited in the world, the Ministry of Environment has appointed S. takesimensis as a preserved plant. The Korea Forest Service also protects it strictly by the law since S. takesimensis is an out-of-the-way plant and possible to be exterminated soon in Korea. Investigation for distribution and ecological characteristics of the habitat for S. takesimensis was carried out in Ulleung-do Island. S. takesimensis has a tendency to emerged with Calystegia soldanella Roem. et Schultb. and Artemisia japonica subsp. littoricola Kitam. C. soldanella community were developed on the dry and well-lighted as east or north facing conditions. A. japonica subsp. littoricola community have tendency to developed on the properly lighted as west or north facing and well maintained soil or air humidity. C. soldanella community were developed on the sandy gravel or gravel and grew with Farfugium japonicum, (L.) Kitam., Lonicera japonica Thunb., and Peucedanum japonicum Thunb.. A. japonica subsp. littoricola communities were emerged on the rock beds or pile of rocks and grew with Sedum oryzifolium Makino, Sedum takesimense Nakai, and Spergularia marina (L.) Griseb..

This study was carried out to provide the basic data for an identifying system for Iris species distributed in Korean market from complete analysing of genetic relationship between three native Iris species and one cultivar bred from the native Iris plant. RAPD analysis of genetic relationship among 4 Irises was possible. According to the RAPD analysis, they were divided into two groups. Among 4 Irises used in this study, Iris laevigata 'Veriegata', Iris laevigata and Iris setosa were classified into the same group since they had many similarities even though the habitat of Iris laevigata in Korean peninsular is restricted mainly in the south and Iris setosa is naturally inhabited in the northern part of Kangwondo. The value for the dissimilarity index of Iris laevigata and Iris laevigata ‘Veriegata’ was 6.757. The value for the dissimilarity index of Iris laevigata and Iris dichotoma was 95.000, so that they were genetically the farthest among them since the genetic relationship between two species are separated far if the value of the dissimilarity index is close to 100.

As the international society becomes more and more open, the international marine transportation demand is growing. And the growth of international tour demands and the developments of new passenger ship routes make the role of passenger terminals crucial. In this context this study analyzes and compares the terminals of Korea and Japan and defines design criteria for the construction of a passenger terminal. As a result of this study, it is proposed that an urban context, an architectural type and spatial characteristics be taken into account for the construction cf a passenger terminal. The ultimate purpose cf this study is to build a future-oriented international passenger terminal based on the result of this study, which will lead the ocean culture.

For a long time, genetic algorithms have been recognized as a new method to solve difficult and complex problems and the performance of genetic algorithms depends on genetic operators, especially crossover operator. Various problems like the traveling salesman problem, the transportation problem or the job shop problem, in logistics engineering can be modeled as a sequencing problem This paper proposes modified genetic crossover operators to be used at various sequencing problems and uses the traveling salesman problem to be applied to a real world problem like the delivery problem and the vehicle routing problem as a benchmark problem Because the proposed operators use parental information as well as network information, they could show better efficiency in performance and computation time than conventional operators.
